@Riot Battle of the Bands!!!

Dear Riot, In Amumu's Emo band skin line Emumu, Tristana is clearly on Bass Guitar and Poppy in behind her playing drums! I'm sure Lulu is singing backup vocals and Kennen is probably on the Electric Guitar! When are these skins coming to League of Legends? Where is the lore? Is there a battle of the bands between them and Pentakill? I NEED THE ANSWERS SOMEBODY PLEASE GET THIS TO THE HIGHER UPS! Someone ping Medler
